Hello Friends @ 3000-L,

Re: MPE/ix unidentified network buffer

Ï duplicated this on our production-box, and, after this (James') message,  
tried it on our test-box (which is more patched; pp6 vs pp4). The result was:  

 Item  Subsystem   Name   G/N  Description      Used   High    Max
____________________________________________________________________
11    NS XPORT           (G)  TCP Control pool    1     22   2048 :)

OK, If I go to my system I see:

:nettool.net.sys;info="res;di"  
...
 22    NS XPORT           (G)  TCP Control pool    1      5   2048 :)
...

Note: The "TCP Control pool" is 11 on your system and 22 on mine since I
have *MANY* more NI's active.

TCP Control Buffer Pool
  
 Description:   TCP Control Buffer Pool is used to pass internal data such as
                configuration data between modules (eg NETCP, TCP SIP/PM, etc)
                . A control buffer is freed once the data is copied to the
                local data structure.
  
 High Value     If the buffer pool is exhausted errors should be logged
 Implications:  indicating a buffer manager error. Any resultant errors
                logged would probably occur at network start (when
                configuration data is read in bulk) and should be reported.
  
 Low Value      NONE
 Implications:
  
 Configuration NONE

OK, not much to tell here. It is a internal buffer pool used to pass messages
between internal HP network modules...  It is not possible to change the  
config size of this pool.   

I can give you 2 hints:

1. The "TCP Control Buffer Pool" is a new item displayed in Nettool.  It is
   very likely this item was added as a result of someone else running into
   this full condition in the recent past.  I re-itterate it would be good
   to install NSTFD10 on this machine.

2. I seem to recollect that the "TCP Control Buffer Pool" also held the  
   buffer pointers to outbound TCP Packet Ack's.  If you have a LAN link
   problem and are having difficulty getting frames on the physical LAN
   cable (due to it being too busy as an example), the "TCP Control Buffer  
   Pool" might start filling up...  i.e. recommend link trouble shooting.
